+## Object Formats
+
+We also infer the format of certain common object shapes, documented below:
+
+### Firestore Timestamps
+
+[Firestore Timestamps](https://firebase.google.com/docs/reference/node/firebase.firestore.Timestamp) are an object with two keys, `_seconds` and `_nanoseconds`:
+
+```json
+{
+  "_seconds": 1642533020,
+  "_nanoseconds": 932000000
+}
+```
+
+Inferring this object will result in the following inferred type:
+
+```json
+{
+  "name": "object",
+  "value": {
+    "_seconds": 1642533020,
+    "_nanoseconds": 932000000
+  },
+  "format": {
+    "name": "firestoreTimestamp"
+  }
+}
+```
